An aquarium can be modeled as a right rectangular prism and it can hold 540 cubic inches of water when it is full. Its width is 6 in and height is 5 in. Find the length of the aquarium in inches. Round your answer to the nearest tenth if necessary.

Therefore ,the volume of the block after cutting out the smaller cubes is  (8/25 cm^2)

Any three-dimensional solid's volume is just the amount of space it takes up. A cube, cuboid, cone, cylinder, or sphere can be one of these solids.

Volumes vary depending on the shape. We have examined different three-dimensional objects and shapes in geometry, including cubes, cuboids, cylinders, cones, and more. We will learn how to calculate the volume for each of these shapes.

Here,

volume = (8/25 cm2) represents the block's volume after the smaller cubes have been removed.

First, we must determine the volume of a cube with four or five centimeter sides, which is:

V = (4/5 cm)^2 = (16/25 cm^2)

The volume of each of the eight smaller cubes that was removed must now be subtracted.

v = (1/5 cm)^2 = (1/25 cm^2)

After the smaller cubes are removed, the block's volume is:

V - 8v = (16/25 cm^2) - 8*(1/25 cm^2) = (8/25 cm^2)

Therefore ,the volume of the block after cutting out the smaller cubes is  (8/25 cm^2)

A cylindrical vase with a curved surface area of 6.79 square metres will cost Rs. 8.14 to paint.

The area with just curved surfaces, leaving the circular top and base, is referred to as the curved surface area. Curved surface area is the amount of space left over after subtracting the cylinder's total circular area. The formula for curved surface area is 2 * pi * r * h.

Here,

We have to calculate the curved surface area of glass in which the flower basket is placed.

Glass is cylindrical,

Height of cylinder = 180cm = 1.8m

Radius of cylinder = 60cm = 0.6m

The curved surface area of the cylinder = 2πrh

The curved surface area of the cylinder = 2*22/7*0.6*1.8

The curved surface area of the cylinder = 6.78584 m²

Cost of painting the glass per m² = Rs. 1.2

Cost of painting 6.78584= 6.78584*1.2

Cost of painting 6.78584= Rs. 8.143

Classification of given triangle is right angle triangle.

Let's suppose a, b and c are the sides of a triangle.

then we know that sum of 2 sides is always greater than third side.

a + b>c

b + c>a

c + a>b

a = 4.35, b = 5.8 , c = 7.25

a + b>c 4.35+5.8 = 10.15>7.25

b + c>a  5.8 + 7.25 =  13.05>4.35

c + a>b 7.25+4.35 = 11.60>5.8

So now we can say given side lengths are representing sides of a triangle.

It generalizes the Pythagorean Theorem, which states that for a right-angled triangle square of the hypotenuse is equal to the sum of squares of the base and height of the triangle, which is [tex]c^2 = a^2 + b^2[/tex]      

Similarly, It can be observed that

The age of Nachelle would be 5 years and the age of Julian would be 7 years.

What is a quadratic equation?

A quadratic equation is a second-order polynomial equation in a single variable x ax²+bx+c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

Let's suppose the age of Nachelle is 'x' years then Julian's age would be 'x+2'.

              x² + [2(x + 2)]² = 139

             x² + 4x² + 8x + 16 = 139

             5x² + 8x - 123 = 0

Let the cost of T-shirt and hat is x and y respectively.

According to the question,

Answer: To find the tip amount in dollars for each order, you need to multiply the total bill amount by the tip percentage.

For the first order of 4 dishes, the total bill amount is $8 per dish * 4 dishes = $<<8*4=32>>32.

The tip amount is $32 * 20% = $6.40.

For the second order of 6 dishes, the total bill amount is $8 per dish * 6 dishes = $<<8*6=48>>48.

The tip amount is $48 * 14% = $6.72.

For the third order of 7 dishes, the total bill amount is $8 per dish * 7 dishes = $<<8*7=56>>56.

The tip amount is $56 * 11% = $6.16.

So, the tip amounts from least to greatest are $6.16, $6.40, and $6.72.

Amount Patrick has to pay back is $ 1680 and the simple interest is $ 280.

What is Simple Interest?

Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.

Simple Interest = ( Principal Amount x Rate x Time Period ) 100

Given data ,

Let the principal amount be = A

The value of A = $ 1400

Let the rate of interest be = r

The value of r = 10 %

Let the number of years = T

The value of T = 2 years

Now , the simple interest is calculated by the formula

Simple Interest = ( Principal Amount x Rate x Time Period ) 100

Substituting the values in the equation , we get

Simple Interest = ( 1400 x 10 x 2 ) / 100

Simple Interest = 14 x 20

Simple Interest = $ 280

Therefore , the simple interest in 2 years is $ 280

And , the total amount Patrick has to give back to the bank is given by the formula

Amount in 2 years = Principal + Interest

Amount in 2 years = 1400 + 280

Amount in 2 years = $ 1680

Therefore , the amount in 2 years is $ 1680

Hence , Amount Patrick has to pay back is $ 1680 and the simple interest is $ 280

171 8 is 1 standard deviations away from the mean is which is 34% area.

So the total area is 81.5%

The relationship between a 90% confidence interval around a mean and a 95% confidence interval around a mean is wider than one other.

Confidence interval:

In statistics, confidence interval means  the probability that a population parameter will fall between two set values.

Given,

Here we need to find the relationship between a 90% confidence interval around a mean and a 95% confidence interval around a mean.

According to the given question, the given confidence interval values are 90% and 95 %.

When we convert this percentage value into decimal, then we get the value as,

90% = 0.9

95% = 0.95

Here a 95 percent confidence interval, you have a 5 percent chance of being wrong.

And with a 90 percent confidence interval, you have a 10 percent chance of being wrong.

Therefore, 90 percent confidence interval would be wider than a 95 percent confidence interval.
